What Wind Forecasts Tell You About Tomorrow
Wind is easy to skip because it is not the headline temperature. Then you step out and the day feels nothing like the number you remembered. Wind changes comfort, dries surfaces, and decides whether light rain falls straight down or blows into a doorway. The speed on tomorrow's forecast is worth a few seconds before you commit to a plan.
The figure next to the high is a daily maximum from the forecast, not a guarantee that every hour will blow that hard. Morning can be nearly calm while afternoon is breezy. That is why each daypart has its own wind line. If the daily max and the morning speed are far apart, the stronger wind is probably later. A planning note appears only when the hourly values actually rise.
A plain scale
Under about 8 miles per hour, the air is light. Leaves move, and clothing can follow the temperature alone. From about 8 to 15 miles per hour, you notice it. Paper slides, and a bike ride into the wind is real work. On a mild day this range is pleasant. On a cool day it is the difference between a sweater and a coat.
From about 15 to 25 miles per hour, loose items start to matter: lightweight chairs, empty bins, a patio umbrella. Rain in this wind will not fall straight down. Above about 25 miles per hour, treat the day as windy even if the sky is clear. This page is not a warning product. A high wind speed is a planning fact. Official wind warnings, if any are in effect, come from the government weather authority.
Read wind next to the temperature
Cool and windy almost always feels colder than the air temperature. Hot and windy can still be uncomfortable heat if humidity is high, because a breeze does not always offset muggy air. Pair the wind with the feels-like value when that value is shown. Pair it with the daypart you care about so you do not cancel a calm morning because the daily maximum looks blustery.
Wind also explains a personal annoyance. An out-and-back walk faces the wind only one way, and that way feels longer. The forecast cannot plan the route. It can tell you the headwind is likely during the hours you picked.
When to stop analyzing it
Choose a speed where your plan gets worse: gardening, a picnic, a bike commute, painting outdoors. When tomorrow's relevant daypart is under that speed, stop. Wind is useful when it changes a decision, and it is clutter when it does not.
If the morning update raises the afternoon wind by a wide margin, look again before you leave lightweight things outside. A one or two mile-per-hour edit is noise. A jump from light to clearly breezy is the change that matters.
